CVE-2025-24111 is a memory corruption vulnerability classified under CWE-119 that affects Apple’s iOS, iPadOS, and several other Apple operating systems. The root cause is improper state management within the system, which can be triggered by a locally executed application possessing limited privileges. This flaw allows the app to corrupt memory in a way that leads to unexpected system termination, effectively causing a denial-of-service (DoS) condition. The vulnerability does not impact confidentiality or integrity but severely affects availability by crashing the system. Exploitation does not require user interaction, increasing the risk if a malicious app is installed. Apple has released fixes in iOS 18.3, iPadOS 18.3 and 17.7.7, macOS Sequoia 15.3, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.3, visionOS 2.3, and watchOS 11.3 to improve state management and prevent this memory corruption. The CVSS v3.1 base score is 5.5 (medium severity), reflecting the local attack vector, low complexity, required privileges, and impact limited to availability. No public exploits or active exploitation have been reported to date. This vulnerability highlights the importance of robust memory and state management in preventing system crashes caused by local applications.

The primary impact of CVE-2025-24111 is denial of service through unexpected system termination on affected Apple devices. Organizations relying on iOS, iPadOS, and related Apple operating systems may experience device instability or crashes if a malicious or buggy app exploits this vulnerability. This can disrupt business operations, especially in environments where Apple devices are critical for communication, data access, or operational control. Although the vulnerability does not compromise data confidentiality or integrity, repeated crashes could lead to productivity loss and potential data loss if unsaved work is interrupted. The requirement for local privileges limits remote exploitation, but insider threats or compromised devices could leverage this flaw. The absence of user interaction requirement increases risk from automated or background processes. Overall, the impact is moderate but significant for organizations with large Apple device deployments or critical reliance on system availability.

1. Apply the official Apple patches immediately on all affected devices, including iOS 18.3, iPadOS 18.3 and 17.7.7, macOS Sequoia 15.3, Sonoma 14.7.5, Ventura 13.7.5, tvOS 18.3, visionOS 2.3, and watchOS 11.3. 2. Restrict installation of untrusted or unsigned applications to reduce the risk of malicious apps exploiting this vulnerability. 3. Implement strict mobile device management (MDM) policies to control app permissions and monitor for anomalous app behavior. 4. Educate users about the risks of installing apps from unofficial sources or sideloading apps. 5. Regularly audit devices for signs of instability or unexpected crashes that could indicate exploitation attempts. 6. Employ endpoint detection and response (EDR) solutions capable of monitoring local app behaviors and memory anomalies. 7. Maintain backups of critical data to mitigate potential losses from unexpected system terminations. 8. For environments with high security requirements, consider additional sandboxing or application whitelisting to limit app capabilities.
